Table of Placards and Initial Response Guide to Use On-Scene

Use the Table of Placards only when the ID Number or proper Shipping Name is not available.

The next two pages display the placards used on transport vehicles carrying dangerous goods with the applicable reference GUIDE circled. Follow these steps:

  1. Approach scene from upwind, uphill or upstream at a safe distance to safely identify and/or read the placard or orange panel. Use binoculars if available.
  2. Match the vehicle placard(s) with one of the placards displayed on the next two pages.
  3. Consult the circled guide number associated with the placard. Use that guide information for now. For example:
    • Use Guide 127 for a Flammable (Class 3) placard Class 3 placards. Square on a point. Red background. Number 3 in bottom portion. Symbol of a flame in top portion. The word “Flammable” or “Combustible” may be in the centre.
    • Use Guide 153 for a Corrosive (Class 8) placard Class 8 placards. Square on a point. White top half, black lower half. Number 8 in bottom portion. In top portion, a symbol of liquid spilling from two test tubes and corroding a hand and a metal bar. The word “Corrosive” may be in the centre.
    • Use Guide 111 when the Danger/Dangerous placard is displayed or

      the nature of the spilled, leaking or burning material is not known. Also use this Guide when the presence of dangerous goods is suspected but no placards can be seen.
    If multiple placards point to more than one guide, initially use the most conservative guide (i.e., the guide requiring the greatest degree of protective actions).
  4. Guides associated with the placards provide the most significant risk and/or hazard information.
  5. When specific information, such as ID number or proper shipping name, becomes available, the more specific Guide recommended for that material must be consulted.
  6. Asterisks (*) on orange placards represent explosives "Compatibility Group" letters. Refer to the Glossary.
  7. Double asterisks (**) on orange placards represent the division of the explosive.
